3 Claims. (Cl. 68-263) This invention relates to improvements in domestic Wringers and other wringers or-squeezers for attachment to electric or other washing machines.

The object of the invention is the provision of trip levers torelease the pressure when desired.

. According to the invention a cover plate is pivoted in or on end caps adapted when closing to rotate a pin on the pivot of the cover to engage heads of spring loaded bolts to apply pressure to the rollers and to engage catches on a trip lever mounted on the pivots of the end caps, release of the trip lever allowing the cover to pivot to relieve pressure.

The invention will be described with reference to the accompanying drawings:

Fig. 1 is a vertical section on line 1-1 Fig. 2 of a wringer according to the present invention,

Fig. 2 is a vertical section of the wringer on line 2-2 Fig. 1,

Fig. 3 is an end view of the trip lever mechanism with the wringer in the operative position.

Fig. 4 is a sectional plan on line 4-4 Fig. 2 showing the trip lever linkage in outside,

Fig. 5 is a section on line 5-5 Fig. 1 showing the trip lever mechanism in the released position.

Fig. 6 is a view similar to Fig. 5 showing the end caps pivoted to separate the rollers.

The wringer is formed with a frame A supporting a lower or bottom driven roller A and an upper or top roller A mounted to rotate in end caps B. The end caps B are pivoted at one end on axle pins b to the heads of bolts B extending through the wringer frame A and provided with coil springs B on their shanks arranged between a nut thereon and the frame A. The opposite ends of the end caps B are connected to the heads B of further similarly mounted springs B on bolts B The heads of the bolts B3 are formed with recesses b to receive pins b passing through axle pins 12 passing through the end caps B, the pressure between the rollers A and A being released when the end caps are pivoted into the position shown in Figs. 5 or 6 and applied when the end caps are in the position shown in Figs. 2.

A cover plate C for the rollers carries the axle pins b when the cover plate is raised as shown in Fig. 5 the pins b have turned and the cap is released from the heads B of the bolts B and the pressure between the rollers is relieved and the end caps B and top roller A may be pivoted into the position shown in Fig. 6 clear of the bottom roller A The cover plate C is formed with pins c projecting from each end and engaging catch lugs d on ballcrank levers D (one at each end of the wringer), whereby the end caps B are retained in the operative position with the rollers A and A in pressure contact by the pins b when the cover C is lowered.

Each bellcrank lever D is pivoted on an axle pin b and is formed with an arm d and a second arm d on which the catch lug d is formed. The arms d at each end of the wringer are connected by a trip rod D and the arms ICE d extend transversely of the wringer. When the trip rod D is moved vertically fron the position shown in Figs. 1 and 2 the catch lugs d are moved away from the pins 0 on the cover thereby releasing the cover which moves into the position shown in Fig. 5 thereby releasing theend caps B from the heads B of the bolts B thereby removing pressure from the rollers and allowing the end caps to be pivoted into the position shown in Fig. '6.

In order to release the pressure from the rollers at both sides of the wringer a second trip rod D is mounted on one arm d of bellcrank levers D pivoted on the axle pins b second arms d of which extend above the free ends of the arms d whereby on an upward movement of the trip rod D the arms d are depressed torelease the cover C.

The release of the pins 0 from the lugs d allows the cover C to move into the position shown in Fig. 5 thereby releasing the pin h under the pull of the springs B from the heads B of the bolts B and relieving the pressure between the rollers A and A In order to. limit the movement of the cover C and prevent it from flying back a slotted link d is mounted on the axle pin.b out-'- side of each of the end caps B, the slot in each of the links 05 being engaged by a pin (i carried by a link d these pins connecting the links d respectively to the links d The links d are mounted on the axle pins b and limit the movement of the cover C to substantially 45.
